7GR-FKS LUBRICATION  OIL PUMP  INSPECTION  


PROCEDURE

Hide 1.INSPECT OIL PUMP RELIEF VALVE

a.
A223653

Coat the valve with engine oil, then check that it falls smoothly into the valve hole by its own weight.

If the valve does not fall smoothly, replace the timing chain cover assembly.

*a Mark


Place the drive and driven rotors into the timing chain cover assembly with the marks facing upward.


b.

Check the rotor tip clearance.

i.
A223655

Using a feeler gauge, measure the clearance between the drive and driven rotor tips.

Standard tip clearance:

0.06 to 0.16 mm (0.00236 to 0.00630 in.)


Maximum tip clearance:

0.16 mm (0.00630 in.)


If the clearance is more than the maximum, replace the timing chain cover assembly.



c.

Check the rotor side clearance.

i.
A223656

Using a feeler gauge and steel square, measure the clearance between the rotors and precision straightedge.

Standard side clearance:

0.030 to 0.075 mm (0.00118 to 0.00295 in.)


Maximum side clearance:

0.075 mm (0.00295 in.)


If the clearance is more than the maximum, replace the timing chain cover assembly.



d.

Check the rotor body clearance.

i.
A223657

Using a feeler gauge, measure the clearance between the driven rotor and body.

Standard body clearance:

0.250 to 0.325 mm (0.00984 to 0.0128 in.)


Maximum body clearance:

0.325 mm (0.0128 in.)


If the clearance is more than the maximum, replace the timing chain cover assembly.
